"Implicit cast from I64 to Int (32 bits) is deprecated" has a wrong position with inline functions.

In this snippet: ([try haxe](https://try.haxe.org/#e3b1F767))

```haxe
inline function pos(): hl.I64 {
return 0;
}
inline function getAt(ret: hl.I64, pos: Int): hl.I64 {
return pos;
}

inline function flipX(v: hl.I64) {
var ret: hl.I64 = 0;
ret += getAt(v, pos());
return ret;
}
var sing: hl.I64 = 5;
var flipedx = flipX(sing);
```
You get the warning `Implicit cast from I64 to Int (32 bits) is deprecated. Use .toInt() or explicitly cast instead.` on the `flipX(sing)` call. Removing the inline on flipX, you get it on the `getAt(v, pos())` call instead (which makes more sense since getAt takes an Int as second argument but pos returns hl.I64)
